CONSTRUCTION 0F ARMOBED-CONCRETE FLOORS AND -CEILINGS.

Application led October 14, 1912.` Serial No. 725,643.

Toall whom t 'may concern: Be it known that I, FRANgoIs CANCALON a citizen of the French Republic, residing at Roanne, Loire, in France, have invente certain new and useful Improvements in the Construction of Armored-Concrete Floors and Ceilings, of which the following is a Thisinventionrelates to improvements in the construction of armored concrete ioors and ceilings, and has for its object a' Hoor or ceiling structure composed' of plaster and armored cement or concrete; the structure is of great resistance, of less thickness than the usual structures of the kind, while possessing considerable sound deadening properties. A

ln the annexed drawings, Figure 1 is a perspective view of a structure according to the invention. Figs. 2 andJ7 3 are sectional views of this structure comprising various anti-resonant devices. Fig. L1 is a section on line #14 of Fig. 3. Figs. 5, G and 7 illustrate various modified structures in section. Figs. 8, 9, 10 are sections of varmored joists or beams adapted to be used in the construc- 4tion of a ceiling or fioor. Figs. 11, 12 and 13l 'are sections of modifications of these beams. Fig. 14 is a cross-section, and Fig/15a longitudinal section of a modied construction.

Figs. 1G to 19 are sectional views of further modifications of construction.

Referring to Fig. 1, a, a indicate `plaster elements forming, by the juxtaposition of two consecutive elements, a groove or space of sufficiently large section to receive an iron bar l) constituting part of the lower armor of the structure. The bars b are embedded in cement c which fillsthe grooves and connects the elements together. In the joints filled with cement ties d are introduced, which support the "iron bars e engaging in hooks of the ties d. These iron bars e which constitute the central part of the armor are covered with a uniform layer of cement or concrete. g intended to form the second part of the structure. When this first layer is formed mold members 7) are arranged thereon between which concretc or cement is ramme so to form beds of a suitable height for lacing the iron bars f in position, said bars eing engaged in upper' hooks of thaties d.

short ends of the' Patented Apr. 8,1913.

and after drying and removaly of the mold members an upper `structure of armored cement is constructed comprising a continuous surface having raised portions or ribs g1. The upper surface of this structure can be rendered uniform by arranging blocks h with inclined edges between theyvarious ribs g1, for instance if the structure is to be covered with a layer of asphalt or other like coating. The spaces between the ribs g1v can be lined with sound-proof material such as sawdust., silicious powder or brick dust.

'If the structure is to be covered with a flooring, resonance can be considerably reduced by employing devices shownin Figs. 2 to 4t. In Fig. 2 suitably spacedbeams 'i are arranged between the ribs g1, on which joists 7' rest, the floor boarding 7:: being fixed on these joists in the usual manner.

l'n the construction shown in Figs?) and 4, the joists are provided with grooves l at the bottom of which is placed an insulating strip m of leather, rubber', linoleum or the like material. An undulating band of wood or steelfwire a is then forced intothe groove l and is held in position by cement or other suitable setting. The bed of cement or concrete g is in this case provided with a groove o obtained by fxinga wooden strip on the under side of mold member p. The joists are .then placed in position so that the lower curves of the bands a are engaged in the grooves 0` the floor boards 7c being then laid on the joists in the usual manner.

The resonance of the structure is considcrably reduced by reducing the free space between the flooring and the structure which can be illedin with a sound absorbing substance in the usual manner, but resonance is principally reduced by the arrangement of the joists which rest on supporting-beams or on undulating metal strips which are slightly elastic and insure excellent insulation.

The armored concrete beams or joists can also be made in the factory and put into place as easily as ordinary iron or wooden beams.

In the construction shown in Figs. 5 and 6 the blocks a have' near their' edges two grooves a)1 al, the metal reinforcements being constituted as before described by b ars b, e, f,connected by ties d; If the armoring is arranged between each joint (Fig. the iiooring can be fixed by means of cement elements j provided with claws g1 which enarmatures at the gage in the grooves al of the blocks and are fixed in position by means of cement. It is .sutiicient then to till the spaces between the elements q with cement tocovereach armature. The elements q form part of the floor and receive either beams z' supporting the joists j on which the ioor boards k are nailed, or ordinary blocks z if the floor is to be constituted by paving or cement.

Then the structure has only to support slight strains it is suteient to provide armoring at each second or third row of blocks, when the use of the members g becomes unnecessary and the form of construction shown in Fig. 6 is suitable. In this case bricks r are arranged in the grooves al, being lheld in place by cement. Cement or concrete' is then rammed in at: g1 so as to completely cover the armature and a permanent strengthened rib is obtained composed of a core of cement yor concrete inset between two rows of bricks. The fiat surfaces of the blocks a separating adjacent ribs can be covered with a layer of cement oi' remain bare and carry the beams which support the `ioor.

Clamping of the blocks is not indispensable and maybe omitted in certain cases. lfhe ties d are in this casestraight as indicated in Fig. 7. The blocks may be solid or hollow. y f

If it is not required to arrange the metal i joints of the blocks, it is possible to make at the factory independentarmored beams-which can easily be transported and placed' into position like ordinary Wooden beams or iron girders. Thus the beamv represented in Fig.

8 is composed of two rows of blocks a separated by the metal armatures previou. y inserted in cement or concrete g1 poured in between the bricks]7 forming a framework. Such beams made beforehand ready for use are arranged juxtaposed in lthe usual manner. These beams may be arranged either with the rib turned upwardas shown in Fig. 9,

,or don award as shown in Fig. 10, for constructing ceilings with visible joists. In this lat-ter form of construction the lower armature 7), arrangedbetween the bricks a, is at the base of the beam. i

Then the beams are tosiipport very heavy weights theA width of their upper surface should be increased. For this purpose the grooves a1 diverge so that the channel formed by t-he'brlick framework 1 is wider at the top asshown in Figs. 11 and 12. The saine arrangement is applicable the brick framework r, r a framework con structed of boards or sheet metal r1 as shown in Fig. 13, which is placed in the grooves al which form exact spacing points. A tter the cement or' concrete poured in betweenv said boards is set, the frame is removed and is again available.'

ing, comprising lsolid rmembers by substitut-ing for' In order that the ceiling composed of plaster and armored concrete may resiststrains to which it may bc Isubjected. it is necessary that the joists or hollow bricks, with crossed jointsl and with or without longitudinal clamping of the bricks together, should form an integral whole. For this purpose, a floor s composed oi' blocks clamped one in another is arranged on the beams as shown in Figs. 14 and 15S or composed of straigliejointed blocks as in Fig. 1S when the weight to support is small. or groored blocks as shown in Fig. li can be used. In any case this tloor is connected to the joists and possibly to the ceiling by cramps t which are either hooked directly on the iron rods f and are embedded at the saine time in the concrete of the joist and in the cement ofthe joint between the bricks .v (tags. 15 and 1G), or are titted by their bent ends t* into the holes u formed in the brick framework r'tFig. 14e)` and lled in with cement.

When straight-jointed blocks are used, as in Fig. 18, the cramps t may be bent over attheir upper ends to facilitate construction; or if the blocks are provided with grooves as in Fig. 17 the end ot the cramps may be rectangular or T-shaped in the cement forming the, joints between the blocks.

iVhen the upper iron rods f are not re:- quired, the cramps f; hook directly on to the rods e (Fig. 19) and insure the static solidityy of the whole of the construction.

The .structure possesses great resistance 'to pressure. rThe ceiling or fiooring can be constructed simultaneously with the kjoists or afterward.
